    A whale's lungs work like ours do, but they make the most of each breath. In one breath, a humans body can absorb about 15 percent of the oxygen inhaled. The whale, on the other hand, absorbs as much as 90 percent of the oxygen it breathes in

    Whales have greater amounts of myoglobin than other animals, allowing them to store larger amounts of oxygen at a time. Whales also make more efficient use of this oxygen. When they dive, their heart beats more slowly and select arteries are constricted.

    As we know whales can't breath underwater but doing the above methods can hold their breath from 40-90 min
